Give full play to the advantages of high efficiency and energy saving of low nitrogen combustor and improve heat utilization rate

With the increasingly prominent role of boiler in industrial production process, it will be particularly urgent to improve the shortcomings of traditional operation mode. In fact, today's boiler transformation scheme has been mature, especially the selection standard for combustion engine has been further refined and clarified, and even played a significant role in improving working conditions through the wide application of low nitrogen combustion engine, Even if pulverized coal is used as fuel, high-temperature eddy current can be generated in a short time during operation, so as to meet the diversified needs of industrial production.

At present, there is a relatively standardized process for the selection of combustion engines, in order to ensure that the corresponding equipment and products can maintain normal operation. After all, many mechanical equipment need to obtain sufficient heat or power through the boiler during operation, but fuels such as pulverized coal often can not be completely burned, which increases the enterprise cost and slows down the development speed, This is also the reason why low nitrogen combustion engine can be favored.

Although the disadvantages of combustion efficiency and labor intensity of pulverized coal burner as fuel are obvious from the perspective of technical principle, if the advantages of high efficiency and energy saving of low nitrogen burner can be brought into full play, it is believed that the heat utilization rate will be greatly improved under the same conditions, especially after the adoption of high-performance and high-quality burner, Whether pulverized coal or other fuels can reasonably improve the heat utilization rate.

The ultra-low nitrogen combustor developed by Zhibo adopts FGR flue gas recirculation technology to suck about 10% - 30% of the flue gas at the tail of the boiler (temperature about 170 ℃) into the air inlet of the combustor through stainless steel flue gas pipe, mixed with combustion supporting air and then entered the furnace. Thus, the temperature and oxygen concentration in the combustion area are reduced, the generation of thermal NOx is reduced, and the NOx emission in the flue gas at the tail of the boiler is less than 30mg / m3.
